在使用 tcolorboxes 时，我发现了一些奇怪的事情。如果框的内容以 center-environment、minipage-environment 或简单的文本开头，则一切看起来都很好。但如果内容以 math align-environment 开头，则存在相当大的差距：
正常情况下它应该是这样的：
有人能帮我消除这个差距吗？我不知道为什么会有这个差距。这里有一个简单的代码示例，如果你想尝试一下：
\documentclass[a4paper, 11pt]{book}
\usepackage[most]{tcolorbox}
\tcbset{framedboxfilled/.style={ enhanced jigsaw,
sharp corners,
colback=white!80!gray,
colbacktitle=white!80!gray,
fonttitle={\bfseries},
coltitle=black,
toprule=1pt, titlerule=1pt, bottomrule=1pt,
leftrule=0pt, rightrule=0pt, right=0pt,
left=-2pt,
}
}
\tcbset{framedboxoutline/.style={%
framedboxfilled,
colback=white,
colbacktitle=white,
}
}
\def\myboxstyle{framedboxoutline}
\newtcolorbox[auto counter,number within=section]{beispiel}[2][]{%
\myboxstyle,
title={Beispiel \thetcbcounter~#2},
}
\begin{document}
\section{Test}

\begin{align*}

&b2 && = && 1111\ 0000\ 1010\ 1101_2\\

答案1
align*，作为垂直模式环境，需要在其自身和其之前的内容之间引入垂直空间。一个简单的解决方案是使用aligned，并将其放置在居中的内联数学中，如\centering$\begin{aligned}...\end{aligned}$。
